介绍

分布式代理锁，动态的锁后缀采用ThreadLocal或者参数名获取 锁粒度自定义选择，目前实现基于redis，后续扩展zk等

软件架构

演示图片

SpringBoot，默认使用redisson链接redis，可以更改注解参数使用Spring redis工具

redis注册(redisson)：

@Slf4j @Configuration public class RedisConfig {

@Value("${spring.redis.host}")
private String host;

@Value("${spring.redis.port}")
private String port;

@Value("${spring.redis.password}")
private String password;

@Value("${spring.redis.timeout}")
private int timeout;

@Value("${spring.redis.pool.min-idle}")
private int minIdleSize;

@Bean
public RedissonClient redissonClient() {
    Config config = new Config();
    config.useSingleServer()
            .setAddress("redis://" + host + ":" + port)
            .setPassword(StringUtils.isEmpty(password) ? null : password)
            .setTimeout(timeout)
            .setConnectionMinimumIdleSize(minIdleSize);
    return Redisson.create(config);
}

}

redis注册(spring.redis)：

使用说明

1. 无后缀（redisson加锁）

   @DistributedProxyLock(key = "SHOP_LOCK_KEY")
   public void test(ShopChainDTO shopChainDTO) {
   for (int i = 0; i < 6; i++) {
   log.info("测试加锁:{}", DistributedProxyLockUtil.get() + i);
   }
   }

2. 参数中获取（redisson加锁）

   ①从某个入参对象的某个参数获取

   @DistributedProxyLock(key = "SHOP_LOCK_KEY", 
       suffixKeyTypeEnum = DistributedProxyLockCommonUtil.PARAM,
       objectName = "shopChainDTO",
       paramName = {"shopId"})   
   public void test(ShopChainDTO shopChainDTO) {   
       for (int i = 0; i < 6; i++) {   
           log.info("测试加锁:{}", DistributedProxyLockUtil.get() + i);    
       }   
   }   
   

   ②从某个入参对象获取

   @DistributedProxyLock(key = "SHOP_LOCK_KEY", 
       suffixKeyTypeEnum = DistributedProxyLockCommonUtil.PARAM,
       objectName = "shopId")  
   public void test(LocalDateTime onlineTime, String shopId) { 
       for (int i = 0; i < 6; i++) {   
           log.info("测试加锁:{}", DistributedProxyLockUtil.get() + i);    
       }   
   }   
   

3. 使用ThreadLocal获取（redisson加锁）

   @Slf4j
   @Service
   public class ShopServiceImpl implements ShopService {

   @DistributedProxyLock(key = "SHOP_LOCK_KEY", 
       suffixKeyTypeEnum = DistributedProxyLockCommonUtil.THREAD_LOCAL) 
   public void test(ShopChainDTO shopChainDTO) {   
       for (int i = 0; i < 6; i++) {   
           log.info("测试加锁:{}", DistributedProxyLockUtil.get() + i);    
       }   
   }   
   

   }

   @RestController @RequestMapping("shop") public class ShopController {

   @Resource   
   private ShopService shopService;    
   
   @PostMapping("/online") 
   @MethodLogger   
   public void run(@RequestBody @Validated ShopChainDTO dto) { 
       DistributedProxyLockUtil.set(dto.getShopId());  
       shopService.test(dto);  
   }
   

   }

4. 无后缀（Spring redis加锁）

   @DistributedProxyLock(key = "SHOP_LOCK_KEY", lockConnectionEnum = DistributedProxyLockCommonUtil.SPRING_REDIS)
   public void test(ShopChainDTO shopChainDTO) {
   for (int i = 0; i < 6; i++) {
   log.info("测试加锁:{}", DistributedProxyLockUtil.get() + i);
   }
   }

5. 参数中获取（Spring redis加锁）

   ①从某个入参对象的某个参数获取

   @DistributedProxyLock(key = "SHOP_LOCK_KEY", 
       suffixKeyTypeEnum = DistributedProxyLockCommonUtil.PARAM,
       objectName = "shopChainDTO",
       paramName = {"shopId"},   
       lockConnectionEnum = DistributedProxyLockCommonUtil.SPRING_REDIS)   
   public void test(ShopChainDTO shopChainDTO) {   
       for (int i = 0; i < 6; i++) {   
           log.info("测试加锁:{}", DistributedProxyLockUtil.get() + i);    
       }   
   }   
   

   ②从某个入参对象获取

   @DistributedProxyLock(key = "SHOP_LOCK_KEY", 
       suffixKeyTypeEnum = DistributedProxyLockCommonUtil.PARAM,
       objectName = "shopId",
       lockConnectionEnum = DistributedProxyLockCommonUtil.SPRING_REDIS)  
   public void test(LocalDateTime onlineTime, String shopId) { 
       for (int i = 0; i < 6; i++) {   
           log.info("测试加锁:{}", DistributedProxyLockUtil.get() + i);    
       }   
   }   
   

6. 使用ThreadLocal获取（Spring redis加锁）

   @Slf4j
   @Service
   public class ShopServiceImpl implements ShopService {

   @DistributedProxyLock(key = "SHOP_LOCK_KEY", 
       suffixKeyTypeEnum = DistributedProxyLockCommonUtil.THREAD_LOCAL,
        lockConnectionEnum = DistributedProxyLockCommonUtil.SPRING_REDIS) 
   public void test(ShopChainDTO shopChainDTO) {   
       for (int i = 0; i < 6; i++) {   
           log.info("测试加锁:{}", DistributedProxyLockUtil.get() + i);    
       }   
   }   
   

   }

   @RestController @RequestMapping("shop") public class ShopController {

   @Resource   
   private ShopService shopService;    
   
   @PostMapping("/online") 
   @MethodLogger   
   public void run(@RequestBody @Validated ShopChainDTO dto) { 
       DistributedProxyLockUtil.set(dto.getShopId());  
       shopService.test(dto);  
   }
   

   }
